Abstract

THIS INVENTION REFERS TO A METHOD OF REGULATING OR ADJUSTING THE TRANSMISSION POWER WHEN SIGNALS ARE TRANSMITTED BETWEEN A MOBILE CONTROL UNIT AND A MOBILE CONTROL UNIT BASED ON A MOBILE TELEPHONE SYSTEM. THE OUTPUT POWER IS REGULATED WITH THE INTENTION TO CONSTANTLY MAINTAIN THE TRANSMISSION POWER AT AN OPTIMAL LEVEL, BY WHICH THE TRANSMISSION POWER IS REQUIRED TO BE THE LOWEST POSSIBLE IN ORDER TO PREVENT AN UNNECESSARY DISTRIBUTION OF NEXT CHANNELS. FREQUENCY, BUT HIGHLY HIGH TO INTERPRET THE TRANSMITTED INFORMATION IN THE RECEIVER. IN ACCORDANCE WITH THE INVENTED METHOD, THE SIGNAL FORCE MEASUREMENT VALUES AND SIGNAL TRANSMISSION QUALITY ARE COLLECTED (1). THE MAIN VALUES OF THE SIGNAL STRENGTH AND TRANSMISSION QUALITY VALUES (2) ARE CALCULATED BASED ON THE COLLECTED MEASUREMENT VALUES. WITH THE HELP OF THE MAIN VALUES CALCULATED, AN ADVANCE VALUE OF SIGNAL STRENGTH (Z_SS) AND TRANSMISSION QUALITY (Z_QQ) AT THE NEXT TIME POINT T SUB 1 HAVE BEEN CALCULATED, SO THAT THE TRANSMISSION POWER IS REMAINING UNCHANGED RELATION TO TRANSMISSION POWER AT INSTANT TIME POINT (T SUB 0) OR PREFIXED. FINALLY, THE TRANSMISSION POWER (MS_PWR) AT THE NEXT TIME POINT (T SUB 1) IS REGULATED BASED ON THESE ADVANCE VALUES (Z_SS, Z_QQ). THE TRANSMISSION POWER (MS_PWR) INCREASES WHEN THE ANTICIPATED TRANSMISSION QUALITY IS POORER THAN THE DESIRED QUALITY AND INCREASES WHEN THE ANTICIPATED QUALITY IS GREATER THAN THE ANTICIPATED SIGNAL STRENGTH IS GREATER THAN THE MAXIMUM VALUE . THE TRANSMISSION POWER OTHERWISE REMAINS UNCHANGED.
